Abstract
The invention relates to a rotary slide valve () of servo-assisted steering systems for motor vehicles that comprises an input and an output element (), which can rotate in relation to one another around a limited angle of rotation, and comprises a coupling connection () of the output element () to a control slide (). A torque-transmitting, non-distorted coupling connection () between the control slide () and the output element () is provided by a coupling pin (), which is fixed inside the output element () and radially extends into a seat of the control slide (). The seat axially tapers to a cross-section that matches the cross-section of the coupling pin (), whereby it is easy to insert the coupling pin () into the seat and possible to attain a play-free supporting position for the coupling pin () by axially displacing the output element () or the coupling pin () and control slide () in relation to one another.
